Redragon COVE K733 vs Epomaker EK21: your questions
The Redragon K733 has a higher specified polling rate of 8000 Hz, which may offer lower latency. It also includes an integrated wrist rest. The Epomaker EK21 has a 1000 Hz polling rate and N-Key Rollover, which is still sufficient for most gaming needs.
The vendor description for the Redragon K733 does not mention any software for key remapping or macro programming. Its customization appears limited to the hot-swappable switches and the dual PC/Calculator modes. For deep key remapping, the Epomaker EK21 with VIA support is the designed choice.
The Epomaker EK21 product listing does not mention a dedicated calculator function or screen. Its primary advantage is programmability via VIA software, where you could theoretically map keys to calculator functions, but it lacks a dedicated display like the Redragon K733.

Only the Epomaker EK21 specifies a battery capacity, which is 1000mAh. The Redragon K733 vendor description does not provide a battery capacity, so runtime comparisons cannot be made from the available information.

The Redragon K733 lists five damping elements: 3.5mm PO foam, IXPE switch foam, PET sound pad, bottom socket foam, and a silicone bottom pad. The Epomaker EK21 specifies three layers: Poron bottom foam, sandwich foam, and an IXPE switch pad.
